Manufactured by Philips Respironics.
Item #DS100
"It seems to be a good solid unit. Quite small even taking the power pack into consideration. It works well and is pretty quiet. The only drawback that I must note is the slight noise on exhale. Others have noted this noise as well. I really don't how to describe it. It is a bit annoying when I first lie down, but I soon tune it out."
"I purchased this machine because money is very tight at the moment and I couldn't afford the nicer ones that keep track of everything!
This machine is comfortable, it does have a ramp feature which is nice, but it is noisy. It makes a different noise on inhalation and exhalation which is very noticable to me even with the tv and a fan on. As I'm using it longer I'm getting more used to it, but it would be much nicer if it made one steady sound!
Overall, not bad for the money."
"This doesn't have all the bell's and whistles of some higher priced machine's but that means there is less to go wrong.
I have two of these with the heated humidifier and have never had any problems. I use the second one when traveling. I would give it five star's but it doesn't have all the bells and whistles."
"It's worth buying. Easy to use, and easy on your wallet."
"I purchased this machine for it's small size to take on a three week trip to the UK, and because I have a larger, older, version which works perfectly. This version works as well as it's older brother, despite it's smaller size. My only complaint, and a very small one at that, is that it makes more noise than the larger one. The pitch changes with inspiration and expiration. Not a loud noise, but noticeable compared to the full size machine. Overall, an excellent machine. I would make the purchase again.
